Question

If a current of 1.54 A flows through the leads of an electrical appliance, how many electrons per second pass through it?

Answer 1

The number of electrons passing through an appliance with a current of 1.54 A is approximately 9.6125 × 1018 electrons per second.

Step-by-step explanation:

The question relates to Physics, specifically to the concept of electrical current in a circuit. The current of 1.54 A flowing through an electric appliance indicates that a charge of 1.54 C (Coulombs) is passing through the circuit every second (since 1 A = 1 C/s). To find out how many electrons pass through per second, we use the charge of a single electron, which is approximately 1.602 ×10−19 C.

To get the number of electrons per second, you divide the total charge per second (1.54 C) by the charge of one electron (1.602 × 10−19 C/electron). This gives:
Number of electrons per second = Total charge per second / Charge of one electron
= 1.54 C/s ÷ 1.602 × 10−19 C/electron
= 9.6125 × 1018 electrons/second
